The design of three-belt mixed model spherical tank's shell partition with larger size steel plate was researched. The relationship between polar region shell partition angle and the size for all shell was analyzed at first, and the range of angle can be chosen at present available steel plate size was given. Then the relationship between polar region shell partition angle and the utilization rate of material was analyzed, and find that around 22.5 degree is optimal selection. Based on this explores, the feasibility and economy for larger scale three-belt mixed model spherical tank's building, and find that the width of available steel plate was the most limited. © 2015, Lanzhou Petroleum Machinery Research Institute.

Point at the 5 000 m3 liquefied petroleum gas erection project, setting the internal construction platform by adopting arc ladder with tripod device has avoided the shortcomings of heavy work of setting scaffolding by adopting steel pipes for internal construction platform of spherical tank with large volume; adopting the phase array (PA) test technology in place of RT examination has enhanced the work efficiency and shorten the time limit of this project and ensured a smoothly implementation as well. This article demonstrates the application for the two procedures mentioned above.

The mixing structure spherical tank has wildly application. Comparing with petal structure, the calculation of geometric size of shell plate shall be more complicated (especially for pole plate). The ways of calculation for shell dimension by 2D work space of AutoCAD soft were introduced, which could be applied on shell plate lofting accurately.
